Making dua for something during salaah

Q: I came across that if I pray for something during my salah, my salah becomes invalid. I have done this many times such as, I prayed ya Allah! My wudu shouldn't break or ya Allah! Give me concentration..does my salah become invalid? 

A: No. Don't do this.

And Allah Ta'ala (الله تعالى) knows best.
